Title: Alginic acid derivs
Inventor: SYED M DR HUSAINI
IPC: A23L29/256
Filed: 1968-12-30
Abstract: Comminuted alginic acid derivative which is water-dispersible (i.e. an algin) is tumbled and during the tumbling water or steam is introduced and the tumbling is continued until the algin is in the form of homogeneous granules. The granules can be dispersed and dissolved readily in water at room temp. with a minimum of stirring. If the treated algin is to be stored, the homogeneous granules are dried and afterwards ground. The amount of water introduced into the algin during the tumbling is suitably from 3 to 500 kg per 100 kg algin. The initial algin is pref. Na alginate but may be any commercial form of algin.

Title: Adjustable support for surround sound speaker system
Inventor: WENG AW KUM
IPC: H04R1/02
Filed: 2000-01-06
Abstract: The present invention is an apparatus 20 and method for projecting audio signals spatially in simulating a surround sound environment. The apparatus features at least a pair of foldable arms 28 extended from at least a pair of poles 23,24 extended from a base 22. Satellite speakers 50, Fig4a are attached to the end of the foldable arms with ball socket plates. The foldable arms are hollow, allowing wiring for speakers to be concealed therein. The foldable arms are also coupled to vertical poles via lockable stoppers 30 that permit users to adjust the spatial placement of the satellite speakers. When the surround sound environment is not required, users can fold the arms and retract the present invention to minimise space requirement. It follows that the present invention simulates a surround sound environment while concealing effectively the wiring for the satellite speakers.

Title: An input device with force feedback
Inventor: MOORE DAVID F
IPC: G05G9/047
Filed: 2000-05-05
Abstract: An input device with force feedback provided by two direct drive actuators 70 comprises a housing (not shown) gripped by the user and a joystick handle 56 manipulable in at least two rotary degrees of freedom. Optical sensors 72 detect a position of the joystick handle and the two actuators 70 each provide torque in a rotary degree of freedom. Each of the actuators is a brushless, single phase actuator having one or two grounded excitation coils (88, Fig.5C) and a moving magnetic material (96). Joystick movement is constrained by pins 71 in slots 73 so that it does not move past either of two limits where the torque output by the actuator in an unenergized state changes direction, and does not move past either local maximum reluctance position adjacent to the local minimum reluctance position which defines a centre position of the joystick handle, the torque and the reluctance both providing a centering spring force on the joystick handle. The input device may be used for computers, games, vehicular control systems or as a television/video remote control.

Title: A method of processing vertical seismic profile data using effective models
Inventor: LEANEY WALTER SCOTT
IPC: G01V1/42
Filed: 2000-07-22
Abstract: A method of applying an effective velocity model to vertical seismic profile (VSP) seismic data comprises correcting for offset using a non-hyperbolic effective velocity model so as to take account of the earth's layering and anisotropy. One preferred non-hyperbolic model for the relationship between offset and travel time is: <EMI ID=1.1 HE=13 WI=111 LX=444 LY=1101 TI=CF> <PC>where <I>t</I> is the travel time of seismic energy from the source to the receiver, <I>x</I> is the offset between the source and the receiver, and <I>z</I> is the depth of the receiver. In a further embodiment of that invention the travel times of direct pulses of seismic energy are used to determine the seismic properties of the earth at depths less than the depths of the receiver. The present invention can also be applied to mode conversion reflections in which, for example, a down-going P-wave is reflected to give an up-going S-wave.

Title: A balanced Pierce crystal oscillator with bias-stabilising loops, and possessing resistance to supply line noise and voltage fluctuation
Inventor: MIDTGAARD JACOB
IPC: H03B5/12
Filed: 2001-12-11
Abstract: A balanced Pierce crystal oscillator comprises two common-base transistors 10 and 11. Oscillation amplitude is controlled by varying the current sources 53 and 54 connected to the emitter nodes 19 and 20. The DC collector voltages on nodes 8 and 9 are stabilised by the bias loop amplifier 44 acting on current sources 46 and 47 to match the common-mode collector voltage to the reference voltage 45. Loop amplifier 41 controls current sources 42 and 43 to null the differential DC voltage on nodes 8 and 9. The use of current sources in both the collector and emitter circuits renders the oscillator insensitive to noise and voltage fluctuation on the supply lines.
Patent GB-2388922-A (GB)
Title: Control system
Inventor: BOWYER ROBERT OWEN
IPC: F02D23/00
Filed: 2002-01-31
Abstract: A method for controlling a system, preferably the emissions of a turbo charged diesel engine, wherein the system is subject to transient changes of target outputs. The target outputs specify outputs required from the system. Steady state information is used to give optimum inputs for the system when the target outputs are substantially constant. A model of the system is used to predict the system outputs in response to candidate new values for the inputs of the system. The steady state information is combined with the predicted response of the system to determine inputs to the system which will cause the system output to match the target outputs as closely as possible. Preferably for each candidate, the method calculates the difference between the steady state inputs and a candidate, and the difference between the target outputs and the predicted outputs that would result from the adoption of that candidate, to determine an optimum candidate which is then used to update the inputs to the system. The system may be used to control the speed of a turbo charger (VGT) and the amount of exhaust gas re-circulation (EGR) so a diesel engine may maintain an air fuel ratio of approx. 25:1 to meet EU Euro 4 or US Tier 2 emission standards.
